A soul may spend many lifetimes learning a specific spiritual lesson. Each life may view the same issue from a different angle and provide a new perspective. These past life regression stories are experiences and perspectives that can help you expand. Because you are a unique part of the cosmic consciousness your experiences of reincarnation also helps expand all knowledge. You actually create in multiple realities and dimensions. Physical reality experiences can be the most challenging. As you may forget who you are and become embroiled in the density of physical matter. By rising above the layers of illusions you can live each life from a fully conscious perspective. If that doesn’t happen then this gives you the opposite experience.
